Just to follow up. I tried the forced update again. This time disabling my firewall and using a patch cable to connect the linkstation directly to my pc. The web interface was still in Japanese and wouldn't accept the default password.
The unit is 1.5 yrs old, so I figured that I had nothing to loose by opening the case to see if anything was loose. Found nothing wrong. I connected the drive direct to my pc with a SATA cable. I could see the drive in the device mgr but not in explorer so I couldn't get to my files.
I packaged everything back up and then tried one last ditch effort to recover the use of the drive. (I gave up on getting the data back.) I did the forced update again, this time I checked the "Rebuild Partition Table" box. I knew that I would loose my data, but hoped that I could at least use the drive. This time the update worked. I was able to get into the web interface.
The unit seems to be working fine now. I have been able to make folders on it and access those folders from my pc. Lesson learned. Even though, the unit comes with backup software. Its not a guaranteed way to backup your files.
